The Sennheiser EW-D ME4 SET is a high-performance digital wireless lavalier system designed for professionals who need reliable, discreet, and crystal-clear audio. Whether you're presenting on stage, leading a seminar, or hosting a live event, this system delivers exceptional sound quality with minimal setup.
At the heart of the system is the ME 4 lavalier microphone—a cardioid, pre-polarized condenser mic that offers high speech intelligibility while effectively rejecting ambient noise. Its compact clip-on design makes it ideal for daily use in dynamic environments where clarity and discretion are key.
The EW-D ME4 SET includes the rugged EW-D SK bodypack transmitter and the EW-D EM rack receiver, both housed in durable metal enclosures built to withstand the rigors of professional use. With digital UHF transmission, the system eliminates interference, static bursts, and noise, ensuring a stable and clean signal across a wide range of frequencies.
Setup is simplified with the Smart Assist App, which replaces complex menus with intuitive mobile control. Automated frequency management ensures fast and reliable connections, even in crowded RF environments.
With up to 2,240 selectable frequencies and a transmission range of up to 100 meters, the EW-D ME4 SET offers exceptional scalability. The rechargeable lithium-ion battery pack provides up to 12 hours of operation, or up to 8 hours with standard AA batteries. The system’s 134 dB dynamic range preserves every detail of your voice, from subtle nuances to powerful projection.
Whether you're on stage, in a conference hall, or broadcasting live, the Sennheiser EW-D ME4 SET delivers professional-grade wireless audio with the precision and reliability you need to perform at your best.
